PILE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 763,161, dated June 21, 1904.

Applicatinn filed July 10, 1903.

To @ZZ whom t may concern.-

,Y the following is a specification. f

I vide a machine in which the saw is automatic-v My invention relates to improvements in pile-sawing machines, and pertains more particularly to that class carrying a pile-driver and in which the piles are cut off after they have been driven into the ground.v

The object of my invention is to provide a machine of this character in which a circular horizontal saw is used and in which said saw is adapted to be moved in the are of a circle and also adapted to be raised or lowered, and thus it will be readily seen that the saw is adapted to cut the piles at any desired height and also adapted to cut the piles in their different arrangement along the line of travel of the machine.

Another object of my invention is to proally fed forward as it works its way through the pile and in which the said saw is moved or caused to be moved at will in the arc of a circle by the main drive-shaft which drives the saw-operating mechanism.

A still further object of my invention is to provide a machine of this character in which the piles may be cut off in a horizontal plane or at an angle, as desired. f

In the accompanying drawings, Figure 1 is a side elevation of my improved machine. Fig. Q is a top plan of Fig. 1. Fig. 3 is an enlarged vertical sectional view of the sawcarrying carriage. Fig. 4 is an enlarged end view of the saw-carriage. Fig. 5 is a transverse sectional'view. Fig. 6 is a longitudinal sectional view of the rear portion of my machine.

Referring now to the drawings, 1 represents a frame which in the form herewith shown is mounted upon wheels 2, but could be mounted upon a boat or any other desired device for which piles are adapted to be used. The said frame 1 is provided with standards 3, which form a frame thereabove, and the forward end of the frame '1 1s provided with a pile-driving Serial No. 165,011l (No model.) I'

frame 4, which carries the usual weight 5, which is operated in the usual manner by an engine 6, which is mounted on the rear end of the frame, and through this mechanism the piles are first driven into the ground and afterward cut, as hereinafter more fully described. The frame l adjacent the forward end is provided with a segmental slot or opening 7, which has communicating therewith the radially-extending slots 8, which are shown live in number; but any desired number may be used, as increasing the number of slots 8 only allows of a finer adjustment of the saws. In rear of said segmental slot 7 is a parallel segmental track 9, upon which is mounted the saw-carriage 10. The said carriage 10 at its rear end is provided with grooved wheels or rollers 11, which are adapted to run on the base 1 just in rear of the segmental slot 7 and adapted to travel in a line parallel therewith.

The rear portion of the frame 1 is provided with the upwardly-extending oppositely-disposed elongated members 13 and 14, and extending transverse thereof` and journaled therein is the main drive-shaft 15, which has one end extending beyond the vertically-arranged member and has rigidly keyed thereon a disk-shaped member'l, which has its outer face provided with ratchet-shaped teeth 17, and loosely mounted on said shaft 15 beyond the member 16 is the main drive-wheel 18, which is slidable thereon. The inner face of said wheel 18 is provided with ratchet-shaped teeth 19, and when the said wheel or gear is moved upon the shaft 15 the teeth 19 interlock with the teeth 17, carried by the member 16, and thus the drive-wheel 18 causes the shaft 15 to rotate. The said wheel 18 maybe moved on the shaft 15 by a lever or any other well-known means, andthe wheel 18 is driven by an engine 20 in any well -known manner carried by the rear end of the frame 1. `The shaft 15 intermediate the two upwardly-ex-2 tending members 13 and 14 is provided with an enlarged beveled gear-wheel 21, which is' base l, but leaving a space between the upl cables 51 and 52, which extend forward and per end thereof and the said transverse bar 22. Pivotally mounted between said transverse bar 22 and the block 23 is a journal 24, which is adapted to oscillate in a vertical .plane Said journal 24 is provided with a transverse opening 25, through which passes the main saw-driving shaft 26, which extends forward and is connected to the saw in a manner hereinafter more fully described. The rear end of said saw -driving shaft 26 is provided with a bevel-gear 27, which is adapted to mesh with the gear 21, carried by the shaft 15, and by means of which the shaft 26 is caused to revolve or rotate and by means of which the saw is revolved. The said block 23 is provided with a transverse opening 28 through vwhich a rod 29 passes, and said rod isfor moving the saw-carriage forward as the saw works its way through the pile. The said rod 29 extends rearwardly through the opening' 28 in the block 23 and has its rear end journaled in a block 30, which extends transverse the frame 1, and said rod extends considerably beyond the block 30, so that the said rod is at all times journaled in said blocks 23 and 3() when the saw-carriage is pushed forward as far as possible. Intermediate the blocks 23 and 30 is a block 31, through which the rod 29 passes. Journaled between said blocks 31 and 30 are two worms 32 and 33, which have their rear journals extending through the block 30 and carry pinions 34 and 35,which are adapted to mesh with each other, and thus the driving of one worm causes the other worm to travel in the opposite direction. The worm 32 has its forward journal passing through the block 31 and mounted on said journal is a pulleywheel 36. The main shaft l5 also carries a small pulley 37, and a belt 38 passes around the pulleys 37 and 36, and thus the two worms are driven in opposite directions. The rod 29 carries an upwardly-extending pin 39, which is normally held between the worms 32 and 33, butis adapted to be thrown in contact with either of said worms. The said rod 29 is provided with an arm 40, which is rigidly secured thereto. Connected to the upper end of said arm 40 is a link 41, which has its opposite end connected to a lever 42, which is pivoted at 43 tothe transverse bar 22. Mounted on said transverse bar 22 is a U- shaped frame 44, which has journaled therein a shaft 45, which is parallel with the shaft 15, and mounted on said shaft 45 is a sleeve 45, which is keyed thereon against rotation, but adapted to slide thereon in either direction. Rigidly carried by sleeve 45/ is a pulley 46. The shaft 15 is also provided with a pulley 47, which is rigidly mounted thereon, and passing around the pulleys 47 and 46 is a belt 48, by means of which the shaft 45 is driven. Loosely mounted on said shaft 45 on each side of the sleeve 45' is a drum 49 and 50, and passing around said drums 49 and 50 are the are secured to the saw-carriage 10, as will be hereinafter more fully described and pointed out. The sleeve 45 is provided on each side with projections 53, and the inner faces of the drums 49 and 50 are provided with projections 54. The sleeve 56 is provided with a groove 55, in which rests the lever 56, which has its lower end pivoted at 57 to the transverse bar 22, and thus it will be seen that the projections 53 are thrown in contact with the projections 54, carried by either of the drums, and thus it will also be seen that either of the drums are revolved, andthe cables secured thereto are wound upon said drum, and the saw-carriage is moved upon the wheelsor rollers in either direction.

The saw-carriage consists of an outer frame mounted upon the two pair of wheels 11 and l2, as heretofore described, which is adapted to be moved in an arc of a circle. Within this outer frame is saw-carrying member 58. rl`he saw-carriage 10 in its lower face is provided with a groove 59, into which slides the bottom 60 of the saw-carrying member 58, and the upper edge of the carriage 10 is provided with grooves 60, which are adapted to receive the top 62 of the saw-carrying member 58. The member has journaled between the bottom 60 and the top 62 a vertical shaft 63, which carries a large pinion 64, which is rigidly secured to the shaft. Below said pinion and carried by the shaft 63 is a beveled gear-wheel 65, which is in mesh with a beveled gear-wheel 66, which is carried by the shaft 67, which jis journaled in the rear wall 68 of the sawcarriage proper, 58. The said shaft 67 has an elongated square portion 68, which is adapted to fit in an elongated square recess 69 in the end of the shaft 26, and thus it will be seen that as the saw-carrying member 58 is moved outwardly the shaft 67 slides within the shaft 26; but both are caused to rotate. The shaft 26 having its inner end journaled in the pivoted bearing 24 is thus allowed to swing in the arc of a circle, the same as the saw-carriage travels in thesame line. The frame 1 is provided with a raised track 7 6, which is also arranged in an are of a circle, and the shaft 26 carries a member 71, in which the shaft 26 is adapted to rotate, and the outer end of said member carries the grooved pulleys 72 and 73, which are adapted to travelv on the track 70, and thus the shaft 26 is supported in a horizontal line, preventing friction or binding between the shaft in thecoupling. The lower face of the saw-carrying member at its forward end is provided with an opening 7 4, in which restsa block 75, which is adapted to oscillate in said opening, and said block having an opening 76, through which a vertically-arranged saw-shaft 77 is adapted to pass, and the upper end of said shaft 77 passing through an elongated transverse opening 78 in the upper portion of the saw-carriage.

IlO

Secured or swiveled to the upper end of said shaft 77 is a block 79, by means of which the said shaft and saw is supported, and secured to the upper end of said block is a supporting'- cable 80, which passes up over the frame 3` and thus it will be seen that the saw-shaft is either raised or lowered, yet it is supported in such a manner that it readily rotates. Mounted on said shaft 77 below the upper portion of the saw-carriage is a pinion 81, which is held against rotation thereon, but yet is adapted to slide on the shaft, thus allowing' of the raising and lowering of the said shaft. The under side of the upper portion of the saw-carriage carries a support 82, which is adapted to support the gear-wheel 81 at its proper height in order that it will at all times mesh with the pinion 64, carried by the vertical shaft 63. The said support 82 has a central supporting' portion 83 and the two outer oblique supporting-walls 84 and 85, which are adapted to support the said pinion 81 in an oblique line when the saw-shaft 77 is moved at an angle to saw the piles at an angle.

The elongated transverse opening 78 in the upper portion of the sawcarriage is provided with a recess 86 surrounding the same, and said recess being' segmental in cross-scction, or, in other words, having its outer ends 87 and 88 gradually curved deeper. The sawshaft 77 above the saw-carriage has surrounding the same a sleeve 89, which is provided with the downwardly-extending portion 90, which is adapted to travel in the segmental opening 78. The said sleeve is provided with an outwardly-extending arm 91, which is pivotally connected to a lever 92, which is pivoted at 93 to the top of the saw-carriage, and thus it will be seen that by moving' said lever in either direction the saw-shaft is thrown and held at an angle. rl`he lower end of said shaft 77 is provided with the usual circular saw 94, which is rigidly secured thereto and adapted to rotate therewith.

The outer end of the rod 29 is provided with a ball 95, which is adapted to fit in a socket 96, carried by the inner end of the rod 97, and the outer end of said shaft is rigidly secured to the movable saw-carriage, and thus it will be seen that the outward movement of the shaft 29 will force the saw-carriage outward and also allow of the carriage moving in the arc of a circle, as heretofore described.

r1`he frame 1 has secured adjacent its outer edge in front of the track pulleys 98 and 99, and passing through or over said pulleys are cables 51 and 52, which have their outer ends 102 and 103 secured to the sides of the sawcarriage and their inner ends passing under the raised track 70 and are secured to the drums 49 and 50.

The lower face of the outer saw-carriage is provided with a slot 104, which allows the saw-shaft to move outwardly when the inner saw-carriage is forced outwardly.

The operation of my machine is as follows: The engine 20 is {irst started, which is adapted to drive the wheel 18, and by means of the clutch member 16 the said wheel is coupled to the shaft 5, and through the medium of the beveled gears 21 and 27, the shaft 26, and the gears 66, 65, 64, and 81 the saw shaft is driven. The saw-shaft, as before described, is raised and lowered by the cable 80, which is secured to the upper end thereof, and thus the saw is raised and lowered, and the piles may be eut at any desired height. Through the medium of a belt 38 and pulleys 36 and' 37 and the -intermeshing gears 34 and 35 the two worm-gears 32 and 33 are driven in opposite directions, and thus when the pin carried by the shaft 29 is thrown in engagement with one of said worm-gears the saw-carriage is pushed forward and when thrown in engagement with the other worm-gear the sawcarriage is drawn backward, and thus the saw is fed as it cuts its way through the pile. Vhen it is desired to move the saw-carriage in an are of a circle to adjust the saw to the different piles, the lever 56 is drawn over, so that the member 53 engages either the drum 49 or 50, and thus the cable is wound thereon and the saw-carriage drawn over toward that side of the frame, while the cable on the opposite drum is free to unwind. The lever 92 is adapted to throw the sawshaft at the desired angle for cutting the piles at any desired angle.
